i915: only use tiled blits on 965+
When scheduled swaps occur, we need to blit between front & back buffers. I
the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit,
only on 965 chips, since it will cause corruption on pre-965 (e.g. 945).
Bug reported by and fix tested by Tomas Janousek <tomi@nomi.cz>.
